Not sure how to report what looks like a bug in S2 Pro?
My apache error logs are FULL of messages like this:
mod_fcgid: stderr: PHP Warning: preg_match(): Compilation failed: missing ) at offset 309 in /AppBuzzinga.com/httpdocs/wp-content/plugins/s2member/src/includes/classes/custom-reg-fields.inc.php on line 696, referer: https://appbuzzinga.com/?s2member_profile=1
It reads like a typo in the source file. It is a warning, but may still be causing issues we haven’t traced yet.
